Typography

GPU Text Rendering for Unity / VRChat

Japanese

Render 32 texts in 1 draw call with high quality. Fully GPU-driven, no C# runtime required.

Performance

Fragment shader instruction counts (Unity compiled shader stats, d3d11):

	Math	Texture	Branch
Typography	920	3	31
SSVFX	3,702	102	201
TexSvfx	5,585	210	255

1/4 fragment instructions vs alternatives. Processing concentrated in Vertex Shader - performance gap widens with resolution.

	Avg	Ratio
Typography	0.471ms	1x
SSVFX	0.851ms	1.8x
TexSV	6.094ms	13.0x

Features

• High-quality edges with MSDF (sharp at any scale)
• Unicode support (Japanese, emoji, ligatures)
• Up to 8 fonts simultaneously
• 5 Root Transforms (hierarchical structure)
• Typewriter / Curve Path / Shake effects
• Outline / Shadow & Glow / Fractal Noise
• Stencil buffer support
• VR Scale adjustment

Installation

1. Import Thry Editor
2. Import Typography unitypackage
3. Set Typography/Mesh.asset to MeshFilter
4. Create Material with Shader: GekikaraStore/Typography

Basic Usage

1. Add fonts in Fonts section
2. Enter text in Text Settings, click "Gen"
3. Adjust Position / Rotation / Scale
